For »Aperture« 119 iris diaphragms and light sensors were arranged in a honeycombed structure. With the aid of an engine, each of the apertures autonomously imitate what happens in a human eye: in darkness the diaphragms are wide open, in bright light they are almost closed. A second mode permits the representation of image data. Using dmx control »Aperture« resembles a display of coarse-resolution pixels. What »Aperture« does not have, however, is a recording brain. Images seen or shown by the object are instantaneously forgotten.
